BURNER.

Specification of Letters Patent.

Patented April 14, 1908.

Application filed May 9, 1907. Serial No.' 3'72,757.

To all whom it may concern:

Be it known that I, GEORGE R. SHANKLIN, a citizen of the United States, residing at Portland, in the county of Multnornah and State of Oregon, have invented new and useful Improvements in Burners, of which the following is a specification.

This invention relates to a burner for furnaces, stoves or other heating apparatus. of tnat type designed for use carbons, and relates more particularly to a burner of that type in which steam is instru mental in gasifymg the fuel and producing therewith a highly combustible mixture whereb the burner can operate with an intense b no flame and without smoke or soot.

The invention has for one of its objects to improve and simplify operation of devices of this character sons to be comparatively easy and inexpensive to construct, thoroughly and readily started and A further object-is the provision of a mixing chamber or cylinder that is heated by the flame and serves as a deflector for the latter whereby the chamber to maintain thcsteam an an efi'ective tem- )erz.ture for vaporizing the liquid hydro-caron discharged into the steam, thus producing a highly combustible mixture and encontrolled.

abling the gas to absorb a large quantity of steam and without causing carbonization and clogging of the burner.

Another object of the invention is the provision of a retort or cylinder having asteam generator therein and connected with separa-te sources of water and fuel supply for delivering water to the generator and oil to the retort to be vaporized and mixed with the steam therein, and also provided witha mixture tube having a jet discharging opening for directing the flame against the retort or cylinder and maintaining it in heated condition, the water and fuel supply pipe being provided with plugs of asbestos or the like through which the liquids pass.

With these objccls in view and others, as will appear as the description proceeds, the

invention comprises the various novel features of construction and arrangement of arts which will be more fully described iereinafter and set forth with particularity in the cl. ms appended hereto.

In the accompanying drawing, which illustrates one of the embodiments of the invention, Figure 1 is a central horizontal section with liquid hydro- I the construction and efficient in practice,

is sulliciently heatedof the burner. Fig. 2 is a vertical central section. line 3-3.

Similar reference characters are employed to designate corresponding parts throughout the several views.

Referring to the drawing, 1 hollow body or retort in the der having closed ends and preferably constructed of comparatively thin walls and fiattened at its bottom. The head 2 of the eylinder or retort is provided with a ertures 3 and 4 into which extend respective y, oil and water su ply pipes 5 and 6 that are provided wit 1 controlling valves 7 and 8. The openings 3 and 4, which are of the same size, are provided with bushings 9 which receive coupling members 10 screwed on the pipes 5 and 6. The discharge end of the pipe 6 is contracted to form a nozzle. Extendlnglongitudinally within the retort or cylinder 1 and at one side of the center thereof is a generator 11 in the form of a tube closed .at its inner ends and threaded into the bushing 9 at the o ening 4, whereby the generator is removaily supported in position. The generator tube 18 disposed over the inner end of the water pipe and at a point intermediate its ends, has a single upwardly discharging o ening 12 by which steam is conveyed to t ie retort 1. In the pipes 5 and 6 are plugs of asbestos and gauze which readily ermit the hydro-carbon oil and water to free y pass into the retort and generator respectively. The tube 11, which is removable through the opening 4 with the bushing 9, extends somewhat short of the head 13 of the retort, and disposed under the latter is an L-shapcd mixture tube 14 having its inner end threaded in an opening 15 arranged in the bottom of the retort and bctwcenthe head- 13 and inner end of the generator 11. The front end of the mixture tube 14 is closed by a cap 16 and the top side of the tube has a; jet discharging opening 17 for directing a jet of vapor upwardly toward the retort.

In practice, the burner is located in the firebox of a furnace or boiler in any suitable position, and to start the burner, a the or flame is kindled under the retort 1 so as to heat the walls thereof to a high temperature. The water valve 8 is sli htly opened to permit a small quantity of water to enter the generator 11, whereupon it immediately vaporizes and escapes through the opening 12 to the retort where it is further expanded and designates a Fig. 3 is a transversesection'= on form of'a cylin- I ging of the burner, the production of a better mixture than is possible where the water and mediately gasified and mixed with the steam :-so that a rich combustible mixture is produced, and this su latter and spread outwardly so as to ta e up su erheated. At about this time, the oil va ve 7 is opened to admit a small quantity of liquid hydro-carbon to the retort, which, upon coming in contact with the hot metal 0 the retort and superheated steam, is irn-' erheated mixture passes out through the tu e 14 and discharges from the burner. The mixture is ignited automatically by the kindling flame, whereupon the latter can be extinguished and removed and the burner will continue in regular operation. The flame 'forcibl impin es on the exterior of the retort am is ba ed b the a large percentage of air and produce a flame 'ing for the liquid posed under the retort and having threaded of great volume for effectively heating the water-back, coils or other heating elements of the boiler or furnace. By introducing the liquid hydro-carbon directly into steam, several beneficial results are obtained, namely, total freedom from carbonizationand clogfuel are vaporized separately and then mixed, since the oil can be vaporized by the steam immediately and take up a larger volume of steam and hence of oxygen.

From the foregoing description, taken in connection with the accompanying drawing, the advantages of the construction and of the method of o eration will be readily ap arent to those ski led in the art to which tie iii-'- vention appertains, and while I have described the principle of operation of the incoupling member secured the fue vention, together withthe apparatus which et opening at an intermediate aving threaded engagement Wit supply pipe, a tube disengagement therewith at one end and arranged to'cause the flame of the burner to heat the retort, and porous plugs in the supply pipes adjacent the discharge ends thereof, and controlling valves in the pipes. 2. A burner comprising aiclosed retort having openings of the same size, bushin s in the openings, a generator supported sole y on one of the'bushings, a water supply pipe extending into the outer end of the generator, a coupling member connectingthe said sup ply p1 e with the bushing, a fuel supply pipe and a exten mg into the second bushing,

pigs to the bushing.
